I have VC Winterwam Small. At various times I'll see the area that covers where the cat is located turn a bright orange. I've seen a couple of posts that indicates that is normal (i.e., the cat is doing it's job), but in doing a Google search, I find that is not what should be happening (i.e., the stove is over firing; or the cat is clogged). What we've done in the past is to open the damper to release some of the heat until the glow disappears. So long and short, which is right? Glow or no glow?
Thanks in advance..
